Sibling name help

Ok so I am back after having my son two months ago. We decided to name him SilasRowanJames. We still want another child but it will be about a year before we try again with IVF. I still have some of the names from my old list but I need some new refreshing ideas. I feel like I have seen the ones on my list a thousand times and want something with more flavor. I need girl and boy ideas please. I would like something that would compliment Silas. Now I know Silas is biblical but I actually don't like biblical names at all. The reason we used the name was because it is in my family history and I liked it before I ever found out it was biblical. So with that said her is my criteria of what I like:

Boys:
NOT biblical necessarily
I like old fashioned but not oldy moldy
stylish
something you have not heard often or lately
preferably nothing in the top 100 for last year
Irish/scottish heritage
Native American heritage
Old english names

Not sure what I can add if you're hard to please...but here are a few. I'm assuming you don't really meant "Old English," as in Anglo-Saxon, because some of the consonant/vowel combinations of those early Germanic names are pretty impossible to get your mouth around (Hrothgar, anyone?), so I'm just going with old-fashioned English or modernized versions of some of those names.
